Alternate Leg ID: LYNCH70485; LYNC 704-85
Area of Operations: Carolina Trough, United States, North America, North Atlantic
Dates: June 09, 1985 to June 30, 1985
Objectives: Determine the velocity structure of the crust at the continent-ocean boundary beneath the Carolina Trough. This information is needed to model the tectonic and thermal process of rifting. Cruise also included the first major deployment of OBSes designed by Bruce Ambuter, after fixing major problems identified in earlier experiments.
Type of Activity: Refraction profiling, OBSes
Information to be derived: Airgun refraction profiles
Explosive refraction profiles
Summary: Explosive refraction data: 465 km; airgun refraction and single-channel streamer data: 305 km; continuous wave source data: 340 km; 3.5 kHz data: 1500 km; USGS OBS stations: 19; Scripps OBS stations: 6; CTDs: 4.
